ABSTRACT:
A two-speed clutch arrangement is disclosed in which an input shaft is drivingly connected to an output drum through a system of clutch shoes so as to alternatively produce direct drive of the output drum, a reduced speed drive, or a neutral condition in which drive is not transmitted to the output drum. The clutch system includes centrifugally actuated primary clutch shoes driven by the input shaft and establishing drive to an inner drum, and two different sets of friction clutches interposed between the inner drum and the output drum. The first set produces a slipping or low speed drive of the output drum, while the second direct drive set controllably establishes direct or high speed drive. Shifting of the clutch arrangement is carried out by a trigger actuator, which activates clutch trigger arrangements associated with the primary clutch shoes and the direct drive clutch set. The trigger actuator is shifted between alternate positions in which either centrifugal actuation of the primary clutch shoes or the direct drive clutch set is allowed. Shifting the position of the trigger actuator prior to establishment of drive to the input shaft being initiated creates a neutral condition of the clutch.
